AUTOMATIC WINDOW ADJUSTER.

Application filed January 3, 1922. Serial No. 526,681.

r '1 all whom it may concern:

lie it known that I, Enwano A. \Vnrer-rr, a citizen of the UnitedStates, residing at lVichita, in the county of Sedgwick and State ofKansas, have invented certain new and useful Im n'ovements in AutomaticVindow Adjusters, of which the following a specification. v v 1 j I Thisinvention relates to a device for maintaining sliding members, such aswindowsin a predetermined position.

may be conveniently supported in any adjusted, position without the aidof counter weights, sash cords, and the ordinary sash supportingarrangement. 1 i

A further object of the invention is the provision of a;' windowadjusting device of detailed description.v

the above describedcharacter, which is very simple in construction,economical to manufacture, compact in appearance, and one which may beinstalled at a relatively low cost. a

A further object of the invention is the provision of a sash retainingmember of the above described character, which is so formed as to beadjustable to the various the same is adapted to support.

Other'objects and advantages will be apparent during the course of thefollowing -]n the accompanying drawings, forming a part of thisspecification, and wherein similar reference characters designatecorresponding parts throughout the several views. :Figure 1 is afragmentary perspective view of 'a window sash member slidable withinitscasing and showing the improved sash adjuster mounted therein.

Figure 2 is a rear elevation of the improvedwindow retainer. 1 F'gure iis a front elevation of the improved window retainer.

Figure 4 is a side elevation of the 11I1- proved window retainer andshowing the same as applied to a sash or other support. F igure 5 is afront elevation of the improvedvsash retainer showing the same inposition for supporting a sash member.

Figure 6 is a 5 front elevation of the improved sash retainer showingthe same in a different arrangement from that shown in Figure 5 for thesash member.

In the accompanying drawings, wherein for the purpose of illustration isshown a preferred embodiment of my invention, the letter A, designates awindow sash or other member adapted for sliding within its supportingcasing B; and which includes the improved. means 0 for maintaining thesame in any adjusted position which an operator may place the same.

The casing B, may of course, be any formation consistent with the use ofthe sliding member A. However, in the case of the ordinary windowcasing, the same will include a parting strip 10, and lateral retainingstrips 11 and 12; said strips 10, 11 and 12 being so positioned as toprovide parallel grooves for upper and lower sash sections of a window.In order to receive the im-. proved sash retaining means C, the frame 18of the sash A is recessed as at 14: inwardly from one side thereof, saidrecess having a side thereof open to directly expose a side of theparting strip 10. a

The retaining means C is of novel formation, and primarily includes thesupporting element 15; roller member 16; and supporting screws 17 and18.

The supporting portion 15 of the in1- proved means C is preferably ofsome resilpurpose of supporting a ient alloymetal, such as hard drawnbrass wire in order to prevent corrosion of the same. This member 15 isbent to provide a pair of arms 20v and 21, the former be ing shorterthan the latter, the juncture point of said arms being looped to providean attaching opening 22. The shorter arm 20 assumes an .acute angle withrespect to the arm 21, and is provided upon its free end with anoutwardly extending looped portion 23, lying in the same plane as theplane defined by the arms 20 and 21; said loop 23 providing an elongatedslot 24 which is substantially concentric with the center of theattaching opening 22, and for a purpose which will'be subsequentlydescribed. The extreme end of the looped portion 23 which lies adjacentthe arm 20 is outturned from the plane defined by the looped portion 28,and provides a pointed spur 26, projecting at right angles to the planeto which said loops 23 and. the arms 20 and 21 lie. The longer arm 21has the lower end 27 thereof bowed outwardly, and on the extreme endproviding a shaft portion 28 adapted for rotatably receiving the rollermember 16 through an aperture 29 provided centrally thereof.

The roller member 16 may be any approved material and is preferablyformed of hard compressed fibl,.l121.ll rubber, or the like; the samebeing retained upon the shaft portion 28 by the overturned split ends 29of the arm portion 21 and which engage the outer face of the rollermember 16 and prevent detachment of the same from the arm 21.

In applying the improved retainer C in the recess 11, the attachingscrew 17 is so fastened into the frame as to support the leg 21 insubstantially a vertical position, and whereby the roller member 16 isheld in frictional engagement with a side.

surface of the parting strip 10, and substantially as illustrated in thedrawings. it will, of course, be necessary to vary the force withwhichthe roller 16 engages the parting strip 10 in order to support thewindow sash A.

Assuming the sash A to be an ordinary light window sash, the compressionin the member 15 which provides the force for frictional enga ementofthe roller 16 with the parting strip 10 is effected by forcing theshorter arm toward the longer arm 21, and driving the spur 2G to biteinto the frame 12. The screw member 18 may then be applied through theelongated slot to prevent lateral displacement of the spin 26 iliron'iits set position. It is presumed that from time to time, it may bedesired to vary the compression with which the roller 16 engages theparting strip 10. This variation of compressive force exerted by thewire member 15, is effected by releasing the securing screw 18 and untilthe spur 26 may be removed from engagement in the frame 13. Simply bypushing the arm 20 toward the arm 21. andt-hen secrn'ing the same inposition by the securing screw 18 :nlditioi'ial compressive force willof course, be provided for forcing of the roller incinher 16 intoengagen'ient witn the casing B for supporting the sash A. Twoadjustments of the improved means C are shown in Figures 5 and (5, theformer illustrating. a light compressive force exerted by the wiremember 15, and the latter illustratiug'the relative positions of thearms 20 and 21 when the maximum compressive force is exerted for forcing-the roller 16 into ongagement with. the parting strip 10. i

It is an important feature of the improved device G that the rollermember 16 is maintained out of direct engagement with the bottom of therecess 1. 1 and whereby the same is held free to rotate as the member Ais slid within the casing 13. This free suspended position of the roller16 is insured by reason of the fact that the split end per-- tions 29 ofthe arm 21 directly contacts the bot-tom of the recess 14: and thusholds the roller member 16 free for rotation on the shaft portion 28.

From the foregoing, it can be seen that a window sash retaining devicehas been provided, which is of extreme utility, in that the samecomprehends the provision of features, which render the same practical.The provision of the loop 23 having its slot 24 therein is an importantfeature of this invention, in that by this arrangement, together withthe securing screw 18, the spur 26 may be positively held in engagementwith the frame 13 in any desired position for assuring retension of theinitial compression force in the Wire member 15 Easy movement of the arm20 overthe shank of the screw element 18 is assured, without entiredetachment ofsaid screwmeniber- 18, and byreason of the fact that theslot- 241 is positioned substantially concentric with. the attachingopening 22.

Various changes in the shape, size and arrangement of parts may be madeto the form of the invention herein shown and described, withoutdeparting from the spirit of the invention or the scope of the claims.

I claim:

1. A sash retainer comprising a resilient wire element bentto provide apair of arms ext-ending at acute angles to each other, said arms havingan attaching loop at their juncture point, one of said arms having itsfree end looped to provide a slot substantially concentric with theattaching loop, and a roller element mounted forrotation upon the freeend of the second arm.
